“I grew up under privileged circumstances and was expected to marry a duke,” she continued. “I spent a lot of time and energy making certain that I would not find myself living a life that had been preordained for me.”

In 2013 Swinton co-founded Drumduan Upper School, a liberal independent school in Nairn, Scotland. The school, which her two children Xavier and Honor attended, has no exams and focuses more on practical classes.

Describing the school to the Observer in 2015, Swinton said: “There’s no grading, no testing at all.”

“My children are now 17, and they will go through this school without any tests at any time, so it’s incredibly art-based, practical learning.

“For example, they learn their science by building a Canadian canoe, or making a knife, or caramelising onions. And they’re all happy 17-year-olds,” she added. “I can’t believe it – happy and inspired.”
